Background: The leptin signaling cascade is a crucial regulator of satiety and energy homeostasis in the hypothalamus, comprising extracellular leptin binding to its receptor, phosphorylation and nuclear translocation of STAT3 (signal transducer and activator of transcription 3) and consecutively the generation of a central satiety signal via neuropeptide secretion. We identified three variants in the extracellular domains of the LEPR gene in two children with severe ...
